We acquired four sets of full-transit ground-based time-series follow-up photometry of TOI-393 and TOI-1201 as part of the TFOPhttps://tess.mit.edu/followup to determine the source of the TESS transit-like signal detection, refine the transit ephemeris, and place constraints on transit depth across optical filter bands. We used the TESS Transit Finder, which is a customized version of the Tapir software package [1]}, to schedule our transit observations. The photometric data were extracted using the AstroImageJ software package [2]}. The transit observation logbook is presented in Table REF , where technical details, such as facility, filter, exposure, or duration, are included. The following paragraphs describe the various data sets obtained from the ground-based facilities.
